采自塔东北地区英吉苏凹陷华英参1井和维马1井的煤系生油岩模拟实验结果表明：煤在Ro为0.65%之后，液态烃产率急剧增加，1.5%之后，迅速降低，其生油高峰约在Ro为1.0%时，每吨有机碳的最大产烃量约为150kg；碳质泥岩与煤岩具有一定的相似性，但液态烃产率受有机显微组分的影响；灰色泥岩的生排油率很低，以生成天然气为主，当Ro接近2.5%时，产烃量接近200kg。根据煤系烃源岩生排烃模拟实验结果，可以建立演化阶段划分标准，另外，煤岩中显微组分的生烃能力还须进一步研究。

Simulatoin test of coal measure source rock was made with thesamples collected from Huaying reference-1 and Weima-1 Wells in Northeast Tarm Basin.The results indicate that when Ro is more than 0.65%,the ratio of liquid hydrocarbon generation increases rapidly;when Ro is greater than 1.5%,the ratio decreased rapidly;when Ro is 1.0%,the ratio is 150 kg/t.c and this is the peak of oil generation.The carbonaceous mudstone is similar to coal measures.The Hydrocarbon generation and expulsion of grey mudstone is low.When Ro is nearly 2.5%,the ratio is near to 200 kg/t.c.The division criterion of evolution stage could be established according to the simulation results.
